Good day everyone. First post but I've been lurking and reading since I purchased my 2015 Q7 TDI (Prestige Package) w/ 57000 back in January.
Now I'm pushing 67,500 miles and have noticed that I'm adding coolant every couple weeks and can smell it burning off engine. Time to delete and get everything cleaned up.
I have the Darkside Development kit in my cart and the SUSTDI kit in my cart but I can't make up my mind. I'm still sourcing new o-rings and gaskets to replace when I do finally decide which kit to go with. Does anyone have experience w/ either kit and would choose one over the other? Pros and Cons? They both look like solid kits and the SUS kit is a bit cheaper. I'm just looking for some more info before I pull the trigger. Going off of pictures of pretty much the same parts isn't doing it for me. I've watched all the vids I could find on youtube and have tried searching here but not much comes up. Unless I'm being a bonehead which is totally possible. Thanks for reading.

I haven't installed it yet, but I just purchased the Darkside kit last week. It is very nicely built.... but it didn't come with any instructions! I think it should be fairly straight forward, yet I am still going to reach out to them to see if they'll send me a PDF. Total price, delivered, was about $320, and it took less than a week to arrive (from UK to Alaska)... faster than Amazon!

I am losing coolant again as well, and I don't have any valley leaks (did that clean up a couple years ago), so I think that the most likely source is the EGR (already disabled) cooler leaking internally. Since it is not in use, I figure, if nothing else, physically removing it eliminates a possibility!

Thanks Wes. Appreciate the info.
Darkside does have a youtube video linked to the EGR delete on their site. Pretty good video (and funny) watching the guy take everything out and getting the new kit situated. Doesn't show him removing the manifold and manipulating all the wiring on top though. I'm still looking around for that as well.

Yeah, it's good to know how that works. I wrote up my process (no video) on another thread that I think is based on 'oil cooler leak'. Has parts lists as well there. I hope to do the removal in the next week or two, so I'll try to record it. I'm terrible at remembering, though. When I'm working, I'm working! I remember to video after it is done. LOL
